2.2 DRH Functions
This section describes the main functions of the DRH.
The Distributed Remote Head (DRH) performs the following functions:
Receives downlink baseband data from the DCU and sends uplink baseband data to the DCU.
Receives RF signals from the antenna system, down-converts the signals to intermediate frequency (IF) signals, amplifies the IF signals, and performs analog-to-digital conversion. The transmit (TX) channel filters downlink signals, performs digital-to-analog conversion, and up-converts RF signals to the TX band.
Multiplexes receive (RX) and TX signals on the RF channel, which enables these signals to share the same antenna path. It also filters the RX and TX signals.
The DRH can be powered by the AC/DC power module. In this case, this DRH is called AC DRH.
An DRH consists of a high-speed interface unit, signal processing unit, power amplifier, and dual-duplexer. Figure 2-3 shows the logical structure of the DRH.
